S PECIFICATION forming part of Letters Patent No. 416,241, datedDecember 3, 1889.

v Application filed September 28, 1889. Serial No. 325,440. (No model.)

To all whom it may concern.-

Be it known that LROBEET D. SCOTT, a citizen of the United States,residing at Pontiac, county of Oakland, State of Michigan, have inventeda certain new and useful Improvement in Road-Carts; and I declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to .make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

Myinvention is designed to produce a roadcart in which the body is sosupported that it may be adjusted to a higher or lower level, asdesired; and it consists, essentially, in the provision of a series ofhooks on the rear end of the shaft over which the hangers or clevises onthe ends of the semi-elliptic spring are engaged. These hooks arearranged one underneath the other, but each one is beyond the verticalline of the one next below it.

My invention also consists in other novel features of constructionhereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of a shaftillustrating my invention. Fig. 2 is a view at right angles to Fig. 1.Fig. 3 is a rear elevation of a portion of a shaft, illustrating avariation of my invention. Fig. 4. shows a rear elevation of a portionof my cart, illustrating how the ends of the semi-elliptic spring areconnected with the hooks.

In carrying out my invent-ion, A represents the shafts, B the axle, andC the semi-elliptic spring for supporting the body. This semiellipticspring is attached about its middle to the body by means of the supportD and, bolts d.

of the semi-elliptic spring by the bolt g.

His a suitable link, one end engaged to the clevis, the other endengaging over the hook. Vhen the hooks are placed on the shafts, asshown in Figs. 2, 3, and at, one end of the link H must be turned atright angles to the opposite end, so that the link can properly en gageover the hooks.

It will be observed that the hook F is outside or beyond the verticalline of the hook F and that the hook F is outside or beyond the verticalline of the hook F. By thus arranging the hooks one beyond the other anyinterference of the link with the hook next below the one in which it isengaged is prevented, and a free and unimpeded action is insured, nomatter in which one of the hooks the link is engaged. This I regard as avery material improvement, since, when the hooks are placed one beneaththe other in the same vertical line, the link or loop, when engaged overthe upper or top hook, would, when the cart is in motion and the bodyswinging more or less, strike the hook next below the one with which it.is engaged and thus prevent free act-ion.

It is of course immaterial whether the hooks be turned inward toward theshaft, as shown in Figs. 2 and 4, or whether they are turned outward, asshown in Fig. 3; but I prefer the former construction, since should thelink or loop become disengaged with a hook it is caught by one of thelower hooks before it allows the body to drop entirely down. By thussupporting the semi-elliptic spring, and consequently the body, by aseries of hooks, and arranging each hook successively beyond thevertical line of the one next below it, any friction or interference isprevented and a much freer action is obtained than has heretofore beenaccomplished. So, also, by forming the hooks in a single piece andcausing them to project in at right angles from the shaft thesemi-elliptic spring, when engaged to the hooks, has a free swingingmotion from front to rear-a result which could not be obtained if thehooks were directly underneath the shafts.

\Vhat I claim is 1. In a road-cart, the combination, with the shafts anda semi-elliptic spring for supporting the body, of a series of hooksattached to said shafts and located Outside of a vertical line throughthe shafts, each successive hook projecting beyond the vertical line oftheme next below it, substantially as described.

2. The combination, with the shafts and a semi-elliptic spring forsupporting the body,

of a series of hooks attached to said shafts and located outside of avertical line through I the shafts, said hooks opening toward saidshafts, and each successive hook projecting beyond the vertical line ofthe hook next below it, substantially as described.

In a road-cart, the eombinatiomwith the shafts and a semi-ellipticspring for supporting the body, of a series of hooks attached to 10 saidshafts and located outside of a Vertical line through the shafts, saidhooks formed in a single casting and each successj ve hook projectingbeyond the vertical line of the hook next below it, substantially asdescribed.

In testimony whereof I sign this specifiea- I5 tion in the presence oftwo witnesses.
